Energy Transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from electrical energy to mechanical energy.

Front

What device transforms electrical energy into mechanical energy?

Back

A fan.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a swing sitting still.

Front

When does a swing have potential energy?

Back

A swing has potential energy when it is sitting still.

Front

What type of energy transformation occurs in an electric hot plate?

Back

Electrical energy is transformed into thermal energy.

Front

What energy transformations occur when a battery-operated radio is used?

Back

Chemical energy is transformed into electrical energy, which is then transformed into sound energy.

Front

What does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

Give an example of energy transformation in a light bulb.

Back

In a light bulb, electrical energy is transformed into light energy and thermal energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object.
